i reference all my engine dealings to novarossi , i really dont know how long a vspec will last after doing this , 4.97-8 is new . cant be too tight as it needs to have room for lubrication

thanks for taking the time to help - please help me make sure I understand this properly - you're recommending to get a new rod for this mill? Piston/sleeve looks fine, the piston still cannot travel "through" the sleeve and stops pretty much where TDC is. No cosmetic damage on the piston/sleeve, at least no scratches I can see.

Can you please confirm I read this right? And could you maybe try to explain howcome this mill is already so worn out despite being only through 1 gallon of good-quality 25%? It might have overheated above 250F a couple of times, but it was always treated respectfully with new air filters pretty much every liter...

Thanks

Paul
